CHARLES WINSLOW, OF LYNN, MASSACHUSETTS.

ELASTIC GORE-CLOTH.

Specification of Letters Patent No. 17,950, dated August 4, 1857.

To all whom t may concern Be it known that I, CHARLES WINsLow, of Lynn, in the county of Essex and State of Massachusetts, have invented an Improvement in the Manufacture of Elastic Gore-Cloth; and I do hereby declare that the same is fully described and represented in the following specification and the accompanying drawings, of which,-

Figure 1, exhibits a strip of gore cloth having its edges turned over and arranged with reference to its warp and-wveft in accordance with my invention.

The elastic fabric on which my improvement is based,pis either one made of common cloth, stretched and worked by an elastic cement, or that for which Letters Patent of the United States of America were granted, on the 6th day of May A. D. 1856, to Henry Gr. Tyer and John Helm, such elastic fabric being composed of two pieces of cloth, either woven or otherwise made with the threads of the weft in a diagonal position or at an acute angle to the threads of the warp, and combined and caused to adhere together by a cement coinposed either of india rubber or gutta percha, the two pieces of clot-h being first united by the compound and the latter being afterward vulcanized or not as circumstances may require.

In carrying out my improvement, I take of such fabric, a strip, of a width somewhat greater than it is to be when finished for being cut into Yelastic gores or made into an elastic band or belt and I turn over and cement down upon the main part of the strip and by a suitable rubber cement or like composition, each edge of the material lapping it upon the main part of the strip about a quarter of an inch or such other distance as may be desirable in order to imitate binding; and furthermore previous to the said strip having its edge or edges so turned down and cemented, each edge to be turned, is to be cut on a line parallel with the filling of the cloth, and at an acute angle with the warp threads in order that when the edge is overlapped and t-urned down, the line of bend of it may be parallel to the lling and at an acute angle with the warp threads. In the drawing, the direction of the warp threads is indicated by black lines at a, a, while those of the filling are denoted by red lines, as shown at b, b, A being the strip of cloth having its opposite parallel edges turned down or overlapped upon the rest of the cloth as shown at c, c, and also in F ig. 2, which is a transverse section of the fabric. By t-hus arranging the overlap with respect to the warp and weft, elasticity is secured longitudinally in the binding so as not to counteract the elasticity of the remainder of the cloth. Furthermore, the edges are prevented from either fraying out or being torn, they being much strengthened.

I would remark that the strip is inelastic widthwise and elastic only in the direction lengthwise or thereabouts. The blue lines f, f, exhibit the manner in which the strip is to be cut into elastic gores, each gore being either of a trapezoidal or triangular shape or an approximation thereto as circumstances may require.

I am aware that an elastic cloth has been made as a shirred fabric. This however differs essentially from the gore cloth made in accordance with my invention.

I do not claim the peculiar elastic cloth as made with its filling arranged at an acute angle with its warp; nor do I claim the elastic fabric as made of two layers of such cloth combined, but- What I do claim as an improved manufacture is,

An elastic band or gore cloth when made not only of a fabric composed of a cement of india rubber or gutta percha and two pieces of cloth in which the warp and weft of each piece are made to cross one another diagonally or at acute anglesl but with -the edges of the cloth cut and overlapped in lines parallel or approximately so to the weft, and at acute angles with the warp threads and cemented down to the fabric as described.

In testimony whereof, I have, hereunto set my signature thisrd day of July A. D.
